In this paper we offer an explanation of the (g−2)μ discrepancy ina R-parity conserving supersymmetric model with right-handedneutrinos in which the right-handed sneutrino is a viable dark mattercandidate. We find that our scenario satisfies all up to dateconstraints including the latest results on (g−2)μ. Sinceright-handed sneutrinos are singlets, no new contributions for δaμ​with respect to the next to minimal supersymmetric Standard Model arepresent. However, the possibility to have the right-handed sneutrinoas the lightest supersymmetric particle opens new ways to escapeLarge Hadron Collider and dark matter constraints. We find that darkmatter masses within 10≲mνR≲600 GeV are fully compatible withcurrent experimental constraints. In addition, future dark matterdirect detection experiments will be able to explore a sizableportion of the allowed parameter space with mνR≲300 GeV, whileindirect detection experiments will be able to probe a much smallerfraction within 200≲mνR ≲350 GeV.p { margin-bottom: 0.25cm; line-height: 115%; background: transparent }
